Solution & Explanation
Answer: (A) A-II, B-I, C-IV, D-III Solution: Heroin (diacetylmorphine) is a depressant that slows down body functions (A-II). Cannabinoids in marijuana are known for their effects on the cardiovascular system (B-I). Cocaine interferes with the transport of the neuro-transmitter dopamine (C-IV). Morphine is a very effective sedative and painkiller (D-III). Why others are wrong: Any pairing that gives heroin a painkiller/cardiovascular role or cocaine a 'slow down' role contradicts NCERT — only A satisfies all four links.
